Hey all I'm new to the forum. I drive a 1999 dodge ram 2500 24 valve cummins. recently I have been having the RPM's drop by 400 Rpms and then go back up. I've checked the tranny and it is for sure not that. I also had my mechanic change the fuel filter thinking it may have been clogged but no luck. my mechanic said he had noticed my stock lift pump didn't kick on every time he turned the switch over and he's not sure if it has a timer or if it is just going out. I personally think it is going out. so my question is this; does it pay to replace the factor lift pump? or could I get an after market lift pump and bypass the original lift pump and hook the aftermarket straight to the fuel filter? Please I really need help here s as it is my only ride to work every day. Thanks a million!

dead pedal as in no response to putting it to the floor? If I'm going about 65 and want to pass someone I'll floor it and it'll take a little bit to increase speed but I always figured it was because it didn't have the horse power to excel in speed like my dads diesel that is at 90 mph before you know it. You think its the throttle response?

I'm short on cash so I ordered the flow max lift pump that was in the mag in the last issue....

well always check stupid *** first. take the banjo off the back of the fuel filter housing ,that is ur main fuel supply from tank an when u bump the key the diesel should shoot out like a baby gizzer,now if it pores like a water hose ur lift pump is screwed.buy a airdog 100 an do away with the *** an u loose ur problems.an run lucase fuel treatment every 2 tanks.

reason why buy air dog or a fass the filters protect ur whole fuel system ,a high preshur pump with no filters is just gonna get it there quicker.

The flow max still is getting run through the original filter plus it has a strainer before the pump, I didn't have the cash to order a more advanced lift pump when I orderd this one on Monday Frown. Thanks for the advice I will use it on my other trucks and I'll keep ya posted if it helps!!

change the fuel filter an before you put it in get a rag an clean the inside of the filter housing cause it probably sat up while getting rebuilt.after u clean the housing fill it up with lucase fuel treatment,problem solved
